賓語從句的時態(tài)問題

1）當主句的謂語動詞是一般現(xiàn)在時時,其賓語從句的時態(tài)可以是任何適當?shù)臅r態(tài).所以,賓語從句的時態(tài)應根據(jù)實際情況而定.

She says (that) she works from Monday to Friday. 她說她從周一至周五上班. （從句是一般現(xiàn)在時）
She says (that) she will leave a message on his desk. 她說她要在他桌子上留個便條. （從句是一般將來時）
She says (that) she has never been to Mount Emei.她說她從來沒有去過峨嵋山. （從句是現(xiàn)在完成時）

2）當主句的謂語動詞的時態(tài)是一般過去時的時候,其賓語從句的時態(tài)一般要用任一適當?shù)倪^去時態(tài).

He said there were no classes yesterday afternoon. 他說昨天下午沒有課. （從句是一般過去時）
He said (that) he was going to take care of the baby. 他說他會去照看這個嬰兒. （從句是過去將來時）
He said (that) they were having a meeting at that time. 他說他們那時正在開會. （從句是過去進行時）

3）但是當賓語從句是表達客觀真理和規(guī)律的句子時,其時態(tài)仍舊用一般現(xiàn)在時.eg.
The teacher told us(that) nothing is difficult if we putour hearts into it.
